On 21 September 1990, Rosario Livatino was killed by mafia mobsters on his way to work. He was an investigative magistrate leading an inquest into corruption and the mafia. Since he was killed, he’s been praised by two Popes, declared a martyr, and last Sunday, on 9th May, he was beatified by the Catholic church. In this episode, host Jonathan Samuels is joined by lawyer Francesco Cavallo who explains what the mafia will do to be impenetrable, and Dr Anna Sergi talks through the story of how this year, the ‘number one enemy’ has been taken to court in a historic trial.
